It's the professorial owl who is teaching his class all about musical instruments. It's manna from heaven for an animator as the entertainingly crafted lyrical narration (complete with slightly annoying singing) takes us all on a very basic lesson in musical onomatopoeia! It was the cavemen who started, rather monotonically, with a dead cow's horn. Next, for the Egyptians it's a different kind of "King Toot" who wants something altogether more sophisticated. Trumpets, dear reader. What happens when trumpets get beaten up; the curvy bits and varying lengths give it flexibility and huzzah, the horn was born. You've got the drift by now and as the other three principal sections of the orchestra: woodwind, strings (quite excruciatingly at times) and finally percussion get an the treatment this leads us to the synchronised, and thankfully more tuneful, modern orchestra. It's a bit too long, this, but it is still quite good fun as they even manage to squeeze the bagpipes in there. The singing doesn't get any better, though - sorry.
